Permissible continuous operating current is ≤ 100 % at ambient temperature of 20 ºC (68 ºF).
NOTE:
I hold = Hold current: maximum current device will pass without tripping in 20 °C still air.
I trip = Trip current: minimum current at which the device will trip in 20 °C still air.
I max = Maximum fault current device can withstand without damage at rated voltage (Vmax)
Pd = Power dissipated from device when in the tripped state at 20 °C still air.
R min= Minimum resistance of device in initial (un-soldered) state.
R 1max= Maximum resistance of device at 20 °C measured one hour after tripping for 20 s.
Caution: Operation beyond the specifi ed rating may result in damage and possible arcing and fl ame.

Features
This product line is designed to provide protec-
tion against induced AC power current, direct
power contact and the natural lightning strike.
The HVR250 product line is widely used in the
fi eld of telecommunications and network-
ing, ISDN and XSDN equipment. It also helps
equipment manufacturers pass ITU K20, K21 and
telcordia requirements.
